Portable cable joint

The invention discloses a portable cable joint, and relates to the field of cable joints, and the technical scheme is that the portable cable joint comprises a first connecting ring and a threaded ring, the exterior of the first connecting ring is in threaded connection with a second connecting ring, the exterior of the second connecting ring is provided with a connecting plate, and one end, away from the second connecting ring, of the connecting plate is provided with a round rod; according to the invention, the first circular plate, the second circular plate, the first fixing groove and the second fixing groove are arranged, the joint of the fixedly connected lines in the cable is placed in the first fixing groove and the second fixing groove, and then the second circular plate is rotated, so that the second fixing groove is not matched with the first fixing groove any more; therefore, the connection part of the internal circuit of the cable is fixed through the non-matching of the second fixing groove and
